Answer:

JK = 20

Step-by-step explanation:

Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle

LK / JK = LM / JM

(45 - JK) / JK = 75 / 60 = 5 / 4

5 JK = 4 (45 - JK)

5 JK = 180 - 4 JK

9 JK = 180

JK = 20

Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:

Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

$\hat{y}=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

$m\approx 2.55,b\approx -6.435$

Substitute these values in (i).

$\hat{y}=(2.55)x+(-6.435)$

$\hat{y}=2.55x-6.435$

Therefore, the correct option is A.

(8/9)^2 I need to evaluate this

tigry1 [53]

(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.
